Illustrative embodiments provide various fatigue reduction devices and methods of manufacture and utilization. The fatigue reduction device may be a stand-alone device or may be integrated with other devices, such as infant carriers, bags, coolers, luggage, or so forth. As used herein, infant carriers, bags, coolers, luggage, equipment, or other carried objects that may or may not include handles, straps, or other carrying mechanisms may be referred to herein as carriers or objects. The fatigue reduction device may also be referred to as a forearm carrier, an elbow carrier, a carrying assistant, or so forth. The fatigue reduction device may secure carriers of any size, shape, or configuration to reduce fatigue, decrease comfort, and increase convenience for a user holding, supporting, or carrying the carrier utilizing the fatigue reduction device.

The fatigue reduction device may be configured to secure or receive straps or handles of the carrier referred to herein as a handle or object. Extensions from the frame of the fatigue reduction device may be utilized to secure the object when utilized horizontally, vertically, or at an angle. The handle or straps may be actively received by the fatigue reduction device (e.g. between the frame and extensions) utilizing a clip, clamp, Velcro straps, slide-in attachment, or other attachment mechanisms. In another embodiment, the fatigue reduction device may passively secure the handle or straps during utilization based on gravity and applied pressure. The fatigue reduction device may include extensions for keeping the straps or handle in place during utilization. For example, fully or partially surrounding extensions in the form of in the form of protrusions, grips, semi-circles, or circular extensions may secure the straps or handle.

A portion of the exterior of the fatigue reduction device or user-faceable portion in contact with the arm of a user may be curved to conform to the shape of an arm of the user. For example, a user contact side of the fatigue reduction device may be concavely shaped to ergonomically fit a portion of the forearm, elbow (crook), and bicep of the user. The curved shape of the exterior of the fatigue reduction device provides additional stability while in use. The exterior or curved portion of the fatigue reduction device that comes in contact with the body of the user may be padded to provide additional comfort to the user as the carrier is carried. In one embodiment, the fatigue reduction device is formed of high-strength plastics with co-molded, integrated, or externally attached padding or cover, such as foam, rubber, or neoprene providing additional padding. In another embodiment, the fatigue reduction device may be composed of thermoplastic, thermosetting plastic materials, wood, metal, polymers, etc. In a further embodiment, the fatigue reduction device may include straps to wrap around the arm of the user to provide additional stabilization and support, and to further assist in preventing the fatigue reduction device from slipping off the arm of the user during use. The straps may be connected by any temporary fastening device, such as Velcro, snaps, clasps, buttons, or magnets that may provide quick and easy attachment and removal of the device by the user. The exterior or curved portion of the fatigue reduction device that comes in contact with the body of the user may also be lined with a semi-sticky material or Velcro that may temporarily stick to and/or grip the clothing of a user during use, to further assist in preventing the fatigue reduction device from slipping off the arm of the user during use.

The fatigue reduction device may have any number of shapes including a reverse seven shape, a flattened u-shaped with widening legs (substantially trapezoidal), a flat shape, a padded sleeve shape, oval shape or a substantially triangular shape. However, the fatigue reduction device may utilize any number of shapes and configurations. The fatigue reduction device may be rested on a forearm of the user, tucked into the crook of the user's arm, fitted around the arm of a user, grasped utilizing a handle, or attached to another device, component, or body part. For example, one or more ends, vertices, or other portions of the fatigue reduction device may include a handle for holding the fatigue reduction device and moving the carrier. As a result, the fatigue reduction device may be carried in various positions depending on the preferences of the user.

The fatigue reduction device may also include a curved or hooked end for attaching or hanging the fatigue reduction device from luggage, a bag, a shoulder, a table, a door, an arm, or other device or component. The fatigue reduction device may also be configured to receive or be fitted with a cover or sleeve for adding additional padding, absorbing sweat and dirt, or for aesthetics. A sleeve may partially or entirely cover the fatigue reduction device. For example, the fatigue reduction device may be used with an infant carrier, and as such, some users may want the fatigue reduction device to match the look, material, design, or upholstery of the infant carrier.

FIG. 1 is a pictorial representation of a fatigue reduction device 100 in accordance with an illustrative embodiment. In one embodiment, the fatigue reduction device 100 may have a reverse seven or L-shape. The fatigue reduction device 100 may include a frame 102. The frame 102 is the main body of the fatigue reduction device 100. In one embodiment, the frame 102 is molded from a single piece of material, such as plastic.

The frame 102 may include an inward, or concave, curve 104. The inward curve 104 is shaped to conform to the forearm, elbow, and bicep of the user. In addition, the entire frame 102 may be inwardly concave (away from the exterior surface) to provide additional support, rigidity, and comfort. The depth of the inward curve 104 may vary between a slight curve and a much deeper curve. The inward curve 104 may extend along the exterior length of the frame 102. For example, the inward curve 104 may be arced (inwardly concave) and extend along a longitudinal axis 105 of the fatigue reduction device 100. In another embodiment, the inward curve 104 may be trapezoidal or triangular groove that may or may not be rounded. The frame 102 is the body of the fatigue reduction device 100 that supports and distributes the weight of the object being carried across portions of the user's arm.

The frame 102 further defines a corner 106. The corner 106 separates a first portion 108 of the frame 102 from a second portion 110. In one embodiment, the first portion 108 may be positioned against the arm (or forearm) of the user, the corner 106 may be positioned against the crook of the user's arm, and the second portion 110 may be positioned against the bicep or upper arm of the user. However, the fatigue reduction device 100 may be utilized or positioned in any number of traditional or untraditional ways, positions, orientations, or configurations that are selected or desirable to the user.

The frame 102 may include extensions 112 and 114. In one embodiment, the extensions 112 and 114 are an integrated portion of the frame 102 that actively or passively secure the handle or object of a carrier. In another embodiment, the extensions 112 and 114 may be separately connected or positioned. For example, the extensions 112 and 114 may be attached at any number of positions, slip to different positions, or replaced with alternatively shaped extensions. The extensions 112 and 114 may be anchor or connection points for a connector, such as a Velcro strap 116. The extensions 112 and 114 may define slits or openings for receiving the Velcro strap 116. The Velcro strap 116 may alternatively be replaced by a band, rope, carabiner, hinged gate, latch, or other connection component.

The extensions 112 and 114 may be configured to define a movement range for a handle of the carrier. For example, the handle or object may be positioned substantially perpendicular to the longitudinal axis 105 along a lateral axis 119 of the fatigue reduction device 100. In one embodiment, the extensions 112 and 114 may allow the handle to rotate slightly for optimal positioning. In another embodiment, the extensions 112 and 114 may closely abut the handle providing firmness and stability.

The fatigue reduction device 100 may include an interior surface 117 and an exterior surface 118. In one embodiment, the interior surface 117 of the frame 102 may be formed of polypropylene. The exterior surface 118 may be formed of a softer material such as foam, rubber, or a softer plastic. In one embodiment, the frame 102 may be molded with the exterior surface 118 being subsequently co-molded to provide a softer surface. Varying portions of the fatigue reduction device 100, such as a handle or space between the extensions 112 and 114, may be coated with an anti-slip material or pattern for stabilization.

FIG. 2 is a pictorial representation of a fatigue reduction device 200 in accordance with an illustrative embodiment. The fatigue reduction device 200 may include many of the components and features of the fatigue reduction device 100 of FIG. 1.

As previously described, the fatigue reduction device 200 may also be utilized by a user grasping a handle 120 (instead of being positioned on the forearm of crook of the user's arm). In one embodiment, the fatigue reduction device 200 may include the handle 120 defined at a first end 121 of the frame 102. The handle 120 may be cylindrically shaped. In another embodiment, the handle 120 may be ergonomically shaped to fit the hand and fingers of the user. For example, the handle 120 may include grooves, finger separators, spindle shape, narrowing and expanding diameters, and so forth. The handle 120 may be particularly useful for carrying bags or other carrying devices with uncomfortable or awkward straps or handles. The handle 120 may also allow the fatigue reduction device 200 to be utilized at a different angle and configuration.

In another embodiment, the handle 120 may be T-shaped (not shown) including a base that extends from the frame 102 and a handle connected to or integrated with the base. The T-shaped handle or portion of the fatigue reduction device 200 may be configured to be secured by the hand of the user with the base being positioned between fingers of the user (e.g. between the middle finger and ring finger) during utilization. The T-shaped handle may similarly have the inward curve 104 for similarly conforming to the shape of the user's arm.

The frame 102 may further define a space 122. The space 122 is an opening or cavity for receiving all or a portion of the user's hands or fingers. In one embodiment, the portion of the frame 102 on either side of the space 122 may be thicker that the rest of the frame to support the weight placed on the fatigue reduction device 200 when the user is utilizing the handle 120.

The frame 102 may further curve at a second end 128 to form a hook 130. The hook 130 and second portion 110 may take any number of shapes depending on the application (e.g. similar to hanger shapes, fish hooks, etc). The hook 130 may curve substantially perpendicular to the second portion 110. In another embodiment, the hook 130 may curve at an oblique or acute angle to the second portion 110. The hook 130 may be utilized to hook, set, or connect the fatigue reduction device 200 on a piece of luggage, seat, holder, table, door, or other component. The tip of the hook 130 may further curve for facilitating connection to another device or component. For example, the fatigue reduction device 200 may be utilized to first carry a duffle bag utilizing an arm of the user as well as subsequently connecting the duffle bag resting on the extension 124 to a roller bag utilizing the hook 130. The fatigue reduction device 200 may be useful for individuals carrying oversized duffle bags with work, sports, hunting, or camping equipment. In one embodiment, the fatigue reduction device 200 may be used while hunting. While hunting, a shotgun or rifle barrel is often rested inside the crook or elbow of a hunter's arm when not being fired. The fatigue reduction device 200 of the present invention may be modified to be used while hunting by removing strap 116 and extension 126, and further modifying extension 124 to support the barrel of a shotgun or rifle. The fatigue reduction device may also be camouflaged in coloration. In another embodiment, the second portion 110 may be elongated for facilitating connection to a luggage handle. The distance separating the extension 126 from the hook 130 may vary based on application. For example, a greater separation distance may facilitate more easily connecting the hook 130. In addition, the curvature of the tip of the hook 130 may vary from a slight curve to nearly curving all the way back on itself. The hook 130 may also be utilized to store the fatigue reduction device 200 (and attached component) when not in use.

Extensions 124 and 126 of the fatigue reduction device 200 are positioned distinctly for receiving and supporting the handle of a carrier. In one embodiment, one or more of the extensions 124 and 126 may be inwardly curved toward the second portion 110 for supporting the carrier when the handle 120 is positioned at the bottom. The extension 124 may support the handle of the carrier when the hook 130 is being utilized or when vertically positioned with the handle 120 at the bottom and the hook 130 at the top. The depth of the curvature of the extension 124 may vary for stabilizing the handle against the extension 124.

FIG. 3 is a pictorial representation of a fatigue reduction device 300 being utilized with an infant carrier 302 in accordance with an illustrative embodiment. As shown, the fatigue reduction device 300 may be carried on the forearm 304, crook 306, and a bicep 308 of a user 310. The fatigue reduction device 300 may further distribute the weight associated with the fatigue reduction device 300.

The fatigue reduction device 300 may be particularly useful when carrying the infant carrier 302 over longer distances. The fatigue reduction device 300 may also be useful for petite users, the elderly, or those with less strength and endurance. The fatigue reduction device 300 may connect to a handle 312 of the fatigue reduction device 300.

FIG. 4 is a pictorial representation of a fatigue reduction device 400 integrated with an infant carrier 402 in accordance with an illustrative embodiment. In one embodiment, the fatigue reduction device 400 may be fixable or slidably integrated with the infant carrier 402. For example, a handle 404 may be substantially semi-circular or U-shaped. The fatigue reduction device 400 may be slidably attached to the handle 404 to move to either of the corners or vertices of the U. For example, the fatigue reduction device 400 may be slid to a bottom portion of the handle 404 for storage. The infant carrier 402 or the handle 404 may even include a receptacle for externally or internally receiving or storing the fatigue reduction device 400.

The fatigue reduction device 600 may be similar to the previous embodiments and include a frame 602, corners 604 and 606, extensions 608 and 610, a bottom face 612, side faces 614 and 616, an exterior portion 618, and a Velcro strap 620.

The fatigue reduction device 600 may be more easily used for carrying an object using a left or right arm or from either direction or user orientation. The extensions 608 and 610 may be utilized to stabilize the object while being carried. In another embodiment, the extensions 608 and 610 may fully or partially encompass the handle of the carrier. For example, the extensions 608 and 610 may further encompass the handle of the carrier by creating a semi-circular shape extending from the frame 602. In this example, the extensions 608 and 610 may be pried or forced open to accept the object. In another embodiment, the Velcro strap 620 may be replaced by a latch or buckle for enclosing the object between the extensions 608 and 610. The extensions 608 and 610 may be curved or straight. In one embodiment, the extensions 608 and 610 include a curved structure 621 for naturally guiding the handle to a middle point of the frame 602 between the extensions 608 and 610.

In one embodiment, each end or tip of the side faces 614 and 616 may include a hook as previously described for hanging or supporting the fatigue reduction device 600. As shown, the angle between the bottom face 612 and side faces 614 and 616 may vary. A more acute angle may facilitate squeezing the fatigue reduction device 600 between the forearm and bicep of the user. A more perpendicular angle may be utilized for applications where the fatigue reduction device 600 rests mainly on the forearm. In another embodiment, the angle between the bottom face 612 and the side faces 614 and 616 may be adjustable. For example, the corners 604 and 606 may be formed of an accordion-like or pivot joint structure that allows for adjustment or all or portions of the fatigue reduction device 600 may be flexible.

FIG. 7 is a side view of another fatigue reduction device 700 being held by a user 701 in accordance with an illustrative embodiment. The fatigue reduction device 700 is similar, in certain respects, to the fatigue reduction device 600 of FIG. 6. The fatigue reduction device 700 may include handles 702 and 704 at ends of the side faces 706 and 708. Spaces 710 and 712 may be defined within the side faces 706 and 708 allowing the user 701 to hold the fatigue reduction device 700 as is shown.

The fatigue reduction device 700 further includes extensions 714 and 716 that are curved and larger for better supporting the object when the user utilizes the handles 702 and 704. If only one side of the fatigue reduction device includes a handle, such as only handle 702, one extension 714 may be larger than the other extension 716 to lend support to the object when the fatigue reduction device is positioned vertically.

Referring now to FIGS. 8-9, a pictorial representation of another fatigue reduction device 800 in accordance with an illustrative embodiment is shown. The fatigue reduction device 800 is triangularly shaped for use for more universal usage from different angles. In various embodiments, the fatigue reduction device 800 may have an equilateral or isosceles shape and configuration.
